I stumbled across this thread and after reading for a bit, went off to find the aerials of the shrine. As founder of the "readable from above" category, and after viewing the site with 3 different lookups (lookdowns?) those being Google maps, Bing! and Terraserver, none of the images would give enough resolution to make the words actually 'readable', so it would not qualify for the category unless Google Earth - or something else - can show a better aerial of the coordinates.
In any case - I welcome other submissions to the RFA category, and I know they are hard to find - I don't even have one WM in my own category, but the rarity is one of the reasons it is distinctive. Jim
